There are, of course, exceptions to that rule, but I generally implement
that rule myself.

Very often, though, switches will overrun a screen by a great deal by
their very nature; when you're implementing a state machine, it is very
difficult to keep that rule for the whole mechanism. Then again,
typically a state machine is implemented once and used forever so it
might not be that big a deal.

There are other constructs or patterns that are also difficult to
implement in a single screen, and there are some systems where the
overhead of function calls takes the advantage of smaller functions
away, though such systems are quite rare today in the general-purpose arena.
